Can Breast Cancer Be Prevented?

Breast cancer risk reflects factors such as age, inherited gene changes, family history, breast tissue, reproductive history, alcohol use, body weight and physical activity. Some factors cannot be changed. Lowering risk is therefore different from removing risk completely.

Risk-reducing care may include checking family history, genetic counselling, medicines for selected people, or preventive breast surgery for people with a particularly high inherited risk. Screening does not prevent a cancer from forming; it can help detect changes earlier. Your options depend on your personal risk and preferences.

Discuss your family history with a clinician, especially if close relatives had breast or ovarian cancer at a young age, or if a family member has a known inherited mutation. Keep physically active, avoid smoking, limit alcohol, and choose eating patterns that support a healthy weight. These steps support overall health while risk remains individual.

Follow the breast-screening plan recommended for your age and risk profile. Become familiar with how your breasts normally look and feel, but do not wait for screening if you notice a new change. A clinician can explain whether genetic assessment or a specialist risk clinic is appropriate.

Make a clinical appointment for a new breast or underarm lump, a change in breast shape, skin dimpling, nipple inversion, bloody discharge, or a persistent one-sided change. These findings can have benign causes, but assessment helps identify the right next step. Seek urgent help for rapidly increasing swelling with fever or feeling acutely unwell.

Ask how your family history affects your risk, whether genetic counselling is suitable, and which screening schedule fits you. If your risk is high, ask about medicines or preventive surgery, their possible effects, and alternatives. Also ask how to check a breast change and when to return if it persists.
